Shells of stars ring quasar in giant elliptical galaxy

These sharp images taken with NASA's Hubble Space Telescope reveal at least five shells of stars surrounding a brilliant quasar at the heart of a giant elliptical galaxy. The image at left shows the quasar, known as MC2 1635+119, and its host galaxy [center] against a backdrop of distant galaxies. In the image at top,right, the shells can barely be seen because of the bright light from the central quasar.
